GRAMMATICAL RULE EXTENSION SYSTEM

摘要

PURPOSE: To provide a syntax rule extension system for automatically generating grammatical rules required for making a syntax unanalyzable sentence syntax analyzable. CONSTITUTION: The syntax analysis of a rephrased sentence having the same meaning as the syntax unanalyzable sentence is performed in a syntax analysis process generation device 2 by using the grammatical rules stored in a grammatical rule storage device 1 and a syntax analysis process is generated. The syntax analysis process for the rephrased sentence is converted to the syntax analysis process of the syntax unanalyzable sentence in a syntax analysis process conversion device 3 and the grammatical rules not included in the grammatical rules among the converted syntax analysis process are extracted in an extension grammatical rule extraction device 4.
